Magazine Date Code help?

[AGG]

I do not know how accurate this is, but here goes (on magazines):

IR- 93
IE- 94
IS- 95
IK- 96
IO- 97
ID- 98
II- 99
OR- 00
NP- 01
AC-02
AD- 03

Can anyone here clarify or supplement (especially after 2004)?

Thanks AGG.

Now did HK only make USP 9 Full Size mags in 1993?

Do the "IR" code USP 9 mags outnumber all others, hence the preponderence to find them more often?

Just trying to figure out why I haven't seen any other code for a USP 9 Full Size 15rnds.

With no, specific information to support, I would not think that HK would only make 15-round, USP magazines in 1993 (e.g., LE-marked or post-2004).
I would further think that HK may have mass-produced the 15-rounders prior to 1994 (high-capacity magazine ban).
I am quite sure that there are magazine experts here that will eventually give you the answers for which you search.

Are there date codes on the USPf40 mags? If so, where is it located on LE marked mags?

[MadMax2012]

Bump.

Does anyone have or has anyone seen a USP 9 Full Size 15 round magazine that didn't have an "IR" code on it?

There has to be an answer to this mystery.

Bumpity Bump.

Any USP 9 Full Size owners that have a 15 round magazine with a date code other than "IR"?

I'm beginning to suspect that the date codes on magazines may not be date codes after all... perhaps product codes for type and caliber?

My P2000 mags have no code at all. (just 9x19 C)

They are Date Codes.

I have 9mm 15-rounds mags with current date codes that match the gun.

Within the last few years HK has changed the way that they have been marking things. Now HK seems to be Date Coding the Slides, Frame, and Magazines with the same codes. Some magazines don't even have codes anymore.
